Title: Device on conversion fittings for upholstered furniture
Inventor: RECKNAGEL ERNST DIETER
IPC: A47C17/175
Filed: 1993-02-11
Abstract: The invention relates to a device on conversion fittings for upholstered furniture for pulling out and pushing in the bedding boxes in combined seating and lying furniture, in which the sitting part and the back part are pivotable relative to one another by a fitting system and are convertible selectively into a piece of seating or lying furniture. The object of the invention consists in providing a device which, during the conversion of the piece of furniture from its seating into its lying function, permits an automatic pulling-out of the bedding box into its conversion-specific pulled-out position, which is possible without special manipulations. This object is achieved according to the invention in that a thrust lever, which acts as a slider crank and is provided with an offset and which is connected in a drive-effective manner via intermediate members to the movable bedding box, is arranged on a supporting yoke assigned, on the one hand, to the back frame and, on the other, to the seat frame and connecting both frame parts to one another in articulated fashion, the intermediate members being formed from a link fixed to the bedding box and a sliding bolt brought into drive-effective form closure with the thrust lever and arranged fixedly at the free end of the link. <IMAGE>

Patent DE-4430387-A1 (DE)
Title: Fault-detection system
Inventor: GOTO KOUJI
IPC: G06F11/07
Filed: 1994-08-26
Abstract: A detection unit (46) detects that an input pattern which is stored in an input-pattern memory (45) corresponds to a signal which is input into a logic circuit unit (2) having arbitrary structure. A prediction pattern which corresponds to the input pattern detected by the detection unit (46) is transferred from the prediction-pattern memory (52) to a comparator (6). The comparator (6) compares an output from the logic circuit unit (2) with the prediction pattern and then a fault-processing circuit (7) processes the comparison result. The fault-processing circuit (7) stores the details of the fault in a fault register (8) and makes the data in the register (8) transferrable via a data bus (34) out from a fault-detection circuit (101b). The information relating to the fault is processed with statistical evaluation and the data stored in the input-pattern memory (45) and the prediction-pattern memory (52) are correctly rewritten, so that the fault-detection rate can be improved. <IMAGE>

Title: Control device for a motor-driven power steering system of a motor vehicle
Inventor: WADA SHUNICHI
IPC: B62D6/02
Filed: 1994-10-25
Abstract: A control device for a motor-driven power steering system of a motor vehicle serves to prevent a clutch producing activation noises without adversely affecting the reliability of the steering system. A power calculation/driver device (91) calculates a motor current instruction value (I0) on the basis of a vehicle speed (V) and a steering torque (T) in order to drive a motor (13). An arithmetic device (901) for a decision reference value for a non-normal torque calculates a decision reference value (T0) for a non-normal torque and a reference time (t0) as a function of the vehicle speed (V) while a load torque calculation device (902) calculates a load torque (TL) on the basis of the steering torque (T) and the motor current instruction value (I0). A motor rotation decision device (907) determines a rotational speed (NM) of the motor (13) from a motor regeneration voltage. If the load torque (TL) is greater than the decision reference value (T0) for a non-normal torque and if its duration (tL) is greater than the reference time (t0), the power supply for the motor (13) is interrupted while a motor fault monitoring/control device (904) is being controlled, on condition that the rotational speed (NM) is not greater than a motor-disabling decision reference rotational speed (N0). Furthermore, a clutch control device (92B) ... in such a way ... Original abstract incomplete. <IMAGE>
